This paper presents non-destructive evaluation of microstructures of heat treated steels by the Magnetic Barkhausen Noise (MBN) method. Various steel specimens having different microstructures were produced by appropriate heat treatments. All specimens were characterized by metallographic examinations, hardness and MBN measurements. The results showed that MBN parameters are highly sensitive to the variations in the microstructure, and this method is a promising candidate for practical non-destructive characterization of heat treated steels.
